[IMail Forum] DNSreport.com: Open Relay Test PASS BUT 554 SPAM-Relay detected

[Geza Levai]

Hello,

Today I ran the dnsreport on our domain and I found a puzzling result in the "Open Relay Test".

I copy/pasted the result here:

Open Relay Test
OK: All of your mailservers appear to be closed to relaying. This is not a thorough check, you can get a thorough one here.
s02.lhaarchitects.com OK: 554 SPAM-Relay detected
mailbag.savvis.net OK: 554 : Relay access denied

So, I ran some tests on our email server and it is NOT an open relay of course, but I am puzzled why the dnsreport still senses some "initial" posibility for us being an open relay.

The main concern of mine is, that if the DNSreport.com has such initial finding, real time spammers would come to the same conclusion and start bombarding our email server with spams by not even bothering checking if we are indeed an open relay.

I ran the dnsreport on "declude.com" because I assumed, that it might be configured right, and indeed the DNSreport showed this result:

Open Relay Test
OK: All of your mailservers appear to be closed to relaying. This is not a thorough check, you can get a thorough one here.
mail.declude.com OK: 550 not local host wwwDNSREPORTcom.example.com, not a gateway

So, does someone has any idea what kind of setting can cause this kind of behavior in theory?

I used the term theory because the front end of our email system is not the Imail server but the my wannagetridof McAfee Webshield SMTP server.
